Block Bolt

Full description of Block Bolt

BlockBolt is the easiest way to instantly start a Minecraft server with your friends — no dashboards, no downloads, no setup. Just join the main hub, click an NPC, and within seconds your very own SMP server is live and ready to play.

It's completely free to start, with time-based access that expands as you vote, refer friends, or join the Discord. When you're done playing, your server spins down to save resources — and spins right back up the next time you log in.
